Re: [mediacapture-screen-share] Add ability to crop a MediaStream obtained through the share-this-tab API (#158)

@zenhack, this would be a very elegant solution if it is indeed possible to make media streams [Transferable](https://developer.mozilla.org/en-US/docs/Web/API/Transferable). But is that really the case? For example, how would you transfer a MediaStream [originating from a canvas](https://developer.mozilla.org/en-US/docs/Web/API/HTMLCanvasElement/captureStream) to a cross-origin iframe? What would that mean for the frames after the transfer? And assuming it's possible, would that not produce an attack vector between these two iframes?
